a cation filed February 7,1925 Serial Names;

.Thisinvention relates to improvements in breast strap slides for harness. In ordinaryharness, the breast strap slide lSfOIlIlGCl of anumber of parts and is not very strong at the points subjected to the greatest strain and, the slidesoften break and furthermore, theslides are usually-provided with non-removable snap hook '1ne1n bers having spring closed locking dogs which, when broken or weakened, require the replacement of entirely new slide members and snap hooks. i

It is one of vention to overpome the before nentioned objectionable featuresand provide a breast;

strap slide whichis so constructed as toreinforce the weakportions and to also permit the replacements of locklng dog spr ngs in a very simple manner.

A further object of the invention is to provide a breast strap slide in which the loop for receiving the martingale strap is positioned to equalize the strain on the breast strap slide.

A further object of the invention is to pro:

vide a breast strap slide having a removable.

snap hook so constructed that when the hook is removed from the slide, the locking dog may be easily removed from the hook to permit replacement of the spring for actuating the dog. c

A further object of the invention to provide a breast stra lide whichfis of simple construction, is strong-and durable;

and is well adapted for the purpose desired;

With the above and other objects in view, the invention consists of the improved breast strap slide and its parts and combinations as set forth in the claims, and all equivalents thereof. 1 i

In the accompanying drawing in which the same reference characters indicate the same parts in all of the views:

Fig. 1 is aside view 0 slide'and the straps connected thereto i Fig. 2 is a central vertical sectional view thereof;

i r Fig. 8 isa top view of the slide member;

Referringto the drawing, the numeral 5 the objects of thepresent inf the improved breast :and'a recessed portion 20 of the. snap to indicates the breaststraprof a harness, 6 the martingale strapand 7 the improved breast v strap slide connected thereto. Said breast strap slide is formed witlra medial curved slide portion 8 and opposite' slots 9 of elongated form through which the breast strap 5 extends in passing beneath the slide portion 8. The slotted portions '9 extend at upward and outward angles from the slide portion 8 to providereini orcing flanges andalso an edge *portions of the slide have downwardly pro ecting eyed extensions 10 for receiving a vboltllwhich is threaded into the eye 10" of the rear extension; A snap hook member '12, havingits upper eyed portionlS interposed between thefextensions 10,"is pivotally supported on the boltll and depends downwardly therefro n. Thethroat portion 13 of said snap is closed by a dog 14 which is formed with trunnions 15 at'its upper end. Said trunnionsjpivotally extend into recesses 16 formed in opposite portions ofthe snap just beneath the transverse eye of the snap, and in co-mmuncation with said bore to permit the removal of the dogwhendesired.

Said snap is also-provided with a T-shaped slot or opening 17 on one side o'f the eyed portion of the snap which opens into-the bore forming the eye, so that when the bolt 11 is removed,fthe dog'may be easily pushed upwardly, so that thetrunnions willdisengage the pivot'recesses 16, and the dog may then be easily separated from the snap by passing the trunnionsthrough the upper portion of the f-shaped opening. The lower or stempart of theT-shaped opening is provided' to accommodatethe stein portion or the dog and permit it to swing inwardly to openposition. The inner-portion of the dog stem is provided with an inwardly extending I pin '18. for receiving a: coiled spring 19 there around which is interposed between'thestem yieldingly hold the dog in looking position against the end portion 12 ofthe snap.-

ion

The dog is provided with side flanges 21 which extend on opposlte sides of the snap reinforce and guidethe dog.

loop of the martingale strap 6 extends as shown in Fig. 1. a

As the parts are thus constructed, the slide portion is reinforced by the martingale loop, and further reinforced by the bolt 11 and the downward extensions 10 which iorm flanges,

and in case the do spring 19 should break;

it can be easily rep aced by removing the bolt 11 and the dog 14.

The slide member can easily play on the a breast strap and a wide surface is provided member having a to prevent wear.

From the foregoing description, it willbe seen that the breast strap slide is of very simple construction and is well adapted for the purpose described. f

What I claim as my invention is: y

1. A breast strap slide, comprising a member having a curved slide portion and opposite slotted portions to receive abreast strap, one edge portion of the member having a transversely extending loop for receiving a martingale strap, said transverse loop being substantially in horizontal alinement with the lower curved part of theslide por tion, lower parts of the slide portion having downwardly projecting eyed extensions, and a hook member pivotally connected to the eyed extensions. i

2. A breast stra slide, comprising a member having a shaped slide portion open at both ends and opposite side slotted portions to receive a breast strap, one edge portion of the membermediallyof its height having a transversely extending loop for re ceiving a martingale strap, said transverse loop being substantially in horizontal aline: ment with the lower curved part of the slide port-ion, lower parts of the slide portion having downwardly projecting eyed extensions, a bolt extending through the eyed extensions, and a hook member pivotally mounted on the bolt.

3. A breast stra slide, comprising a -shaped slide portion and opposite side slotted portions above the lane of the Ushaped part to receive a roast strap, one edge portion of the member medially of its height having a transversely extending loopfor receiving a martingale strap, lower parts ofthe slide portion having downwardly projecting eyed extensions, :1 bolt extending through the eyed extensions, a hook member pivotally mounted on the bolt between the eyed extensions and provided with recessed portions adjacent the bolt, and a spring actuated dog detachably and pivotally mounted in the recessed portions for yieldingly locking the throat of the hook member and being easily detachable from said hook member when the bolt is partly withdrawn from said hook member.

4. A breast stra slide, comprising a member having a lJ-shaped slide portion and opposite side slotted portions above the plane of the U-shaped part to receive a breast strap, one edge portion of the member medially of its height having a transversely extending loop for receiving a 1nartingale strap, lower parts of the slide portion having downwardly projecting eyed extensions, a bolt extending through the eyed extensions, a) hook member pivotally mounted on thebolt between the eyed extensions and provided with. recessed portions adjacent the bolt, and a spring actuv ated dog having trunnions which pivotally extend into the recessed portions for yieldingly locking the throatof the hook member and being easily detachable from said hook member when the bolt is partly withdrawn from said hook member.

5. A breast strap slide, comprising a member having a U-shaped slide .portion and opposite side slotted portions above the plane of the U-shaped part to receive a breast strap, one edge portion of the member medially of its height having a transversely extending loop for receiving a martingale strap, lower parts of the slide portion having downwardly .projecting eyed extensions, a bolt extending through one eyed extension and having a threaded engagement with the other eyed extension, a hook member pivotally mounted on the bolt between the eyed extensions and provided with a side opening in communication with the bow througlrwhich the bolt extends, said hook member also having recessed portions opening into the borefa locking dog having trunnions which enter the recesses throughthe side openingto pivotally con nect the dog to the hook member, said dog being detadhable from the hook member when the bolt is partly removed, and a spring means interposed between the dog and the hook member for yieldingly hold ing the dog in a locking position.
